Brokenhearted,
When I disclosed to my ex-wife in 2002, it was the first time I had ever even hinted at CSA to anyone. She was in an affair at the time, and I don't know why I disclosed then, except that I was desperate to "save" my marriage and my family.
I talked her into marriage counseling, and two years later she was with another guy. We had continued to see the marriage counselor, but by that time I had a different T for my CSA recovery work. When I told T about this new affair, she was not surprised. It took me a month or two to realize that, and I asked her why she hadn't seemed surprised. She told me that from my descriptions my ex had never sounded "particularly stable" and explained how a lot of relationships can go south if one partner starts getting healthy and the other feels threatened by that.
I still wanted to "save" my marriage back then, but the guy's wife came here to confront my ex on our porch. Within a week or two, my ex was sleeping with another different guy. It turned out that the one I discovered in 2002 wasn't the first. I wasn't the only one with unhealthy behaviors, but I was the one who upset the apple cart by working to change.
So it was more likely that my recovery, rather than my issues, posed a threat.
Thanks,
Joe
